This invention refers to an adding machine with indicating and tens transfer mechanism, and the chief object of the invention is to provide such a machine which requires a minimum of space and thus can be used to advantage for instance in a portable ticket printing apparatus or the like, in which the space required by the adding machine as well as its weight are of essential importance. A further object of the invention is to provide an easily operated adding machine, which by printing or like indication is able to show the single figures or amounts entered as well as the total thereof, the latter indication being the result of an operation, which is not identical with the operation serving to enter the tigures in the machine, and this latter operation is preferably eifected by means of a key.

The invention refers to the type of adding machines known per se, which has arched amount setting members actuating, when angularly displaced about their centre, radially displaceable teeth a varying number of which is caused to displace against the centre of motion of the amount setting members when the latter are turned into the different setting positions, the actuated teeth being intended to co-operate with counting wheels, which are caused to accumulate the figure or amount determined by the number of teeth actuated. The present application is a continuation-impart of application Serial No. 83,322, filed March 25, 1949, and now abandoned.

The invention will be described in detail in the following text, reference being had therein to the accompanying diagrammatic drawings, whereby the features of the inventional idea will become evident. It must be pointed out, however, that for elucidating purposes the drawings show a machine with portions broken away to facilitate the understanding of its functioning and with gear wheel structures abnormally extended in the axial direction, which of course is not found in a practical embodiment. The machine illustrated` in the drawings is primarily intended for use in a portable ticket printing apparatus, thus presenting an embodiment of the invention which within certain limits may be modified to suit another purpose. In the drawings:

Fig. l is a perspective view'of the adding machine, which is normally fitted with ve amount setting members with pertaining radially displaceable teeth, four of which however are broken away for revealing the accumulating and indicating mechanism of the machine, the latter in turn being partly broken away to facilitate the tracing of the machine operations.

Fig. 2 shows a portion of the machine corresponding to the remote part of Fig. 1 at a stage when the set amount is being entered into the accumulator of the machine.

Fig. 3 also is a partial view of Fig. 1, but shows a stage when the accumulator is performing a tens transfer actuated by a rigid tooth in the frame of the machine.

Fig. 4 is a partial view of the operative parts of the machine while transmitting the positions of the counting wheels to the indicating mechanism, which operation may also be denominated a reading off or an emptying Generally speaking, the machine according to the invention consists of three main parts, viz, for the tirst thing a set of amount setting members each similar to the single setting member 1 illustrated in Fig. 1, although in the machine herein described tive such members are required, for the second a rotatable frame structure 2 with pertaining driving mechanism 3, said frame construction accommodating the counting wheels accumulating the set amounts, as well as a tens transfer mechanism connecting in pairs the accumulating wheels for the different decades, and for the third an indicating mechanism 4 which is normally actuated directly from the different amount setting members 1 for adjustment into positions corresponding to the positions of the amount setting members 1 when enter' g a certain amount or figure into the machine, but which is also capable to show the total of the amounts or figures entered into the machine as will be described later on in this text.

The outstanding and chief feature of the machine is the rotating frame 2, which carries the counting wheels and tens transfer means. The other parts of the machine may be varied by the expert within wide limits and are known for essential part from machines of similar kind, although in connection with the rotating frame they constitute a new and expedient combination.

The frame 2 is rotatable about shaft pivots 5 journalled in a suitable way in a machine frame, which is not shown in the drawing, and the rotation of the frame is effected by means for an operating lever 6 which is swingably journalled in the machine frame and via a toothed sector 7 engages a toothed ring 8 mounted on a sleeve 9 which is rotatable coaxially with the shaft pivots of the frame 2, said sleeve 9 further carrying a toothed rim 10 with set teeth arranged to co-operate with a spring-actuated catch 11 provided at one end of the frame 2, so that the frame 2 is caused to rotate in one direction only at each actuation of the operating lever. In the machine shown the frame 2 is thus caused to rotate anti-clockwise in the direction indicated by the arrow 12, when the operating lever is moved forwards in the direction indicated by the arrow 13, whereas the frame 2 remains in its position, retained by special brake means not shown in the drawing when the operating lever 6 is restored to its initial position. The driving mechanism 3 for the frame 2 is so adapted, that the frame is caused to accomplish exactly one whole revolution each time the operating lever 6 is swung forwards by a distance corresponding to or exceeding the centre angle of the toothed sector 7. The operating lever 6 is suitably restored to its initial position by means of a spring (not shown in the drawing). The driving mechanism illustrated in the drawing is chosen wholly arbitrarily and may be replaced with any other driving device, by means of which the frame 2 can be intermittently rotated by one revolution about its axis of rotation to allow the adding function of the machine.

As already mentioned, the frame 2 represents the heart of the machine, and it includes, mounted on shafts 14 and 15 respectively which are eccentric relative the axis of rotation of the frame proper, a series of coaxial counting or accumulating wheels 20, 21, 22, 23 and 24 journalled so as to be freely rotatable on the shaft 14 but prevented from moving axially in the frame 2, which wheels are representing the different decades in the adding machine and are all of them provided with ten teeth, and further a series of tens transfer members 25, 26, 27 and 28, which are journalled on the shaft 15 so as to be freely rotatable but prevented from moving axially in the frame 2 and which are intended for transmitting the tens from the counting wheels of a lower decade to the counting wheels of the adjacent higher decade. Each counting wheel 20-23 is equipped with a hub sleeve 29 carrying at a certain axial distance from the teeth of the respective counting wheel a radially projecting tooth 30. Said tooth 30 assumes such an angular position relative the teeth of the counting wheel that it will enter a clearing between two counting wheel teeth, and it serves to actuate the adjacent tens transfer member in a manner to be described later on in the text. The remote counting wheel 24 of the machine shown is without tooth 30, since said counting wheel represents the highest decade of the machine. However, there is nothing to prevent that for the sake of uniformity also this wheel is equipped in the same manner as the other counting wheels.

Each tens transfer member consists of a hub sleeve, at one end of which (the front end in the drawing) are mounted two gear wheels 35, 36 adjacent one another, the other end of the sleeve carrying a third gear wheel 37. Each gear wheel 35, 36 and 37 respectively on the tens transfer members 25-28 is provided with four teeth only, which are at right angles to each other, but the wheels are so large that the distance between the teeth of each wheel represents three pitches. In other words it may be said that the gear lwheels 35, 36 and 37 represent twelve-toothed wheels having some teeth removed and only every thirdtoothleftf The tonthrnodule of said gear wheels "35"k '36'3a`d" 3.7fatiech tens transfer 'member fs meente as.'@mettte-cernng'wi-ee1s.'the tooth e0 of the counting wheels ralso, being ltriade according to this module.

The remote gear wheel 37 on the tens transfermernber, the teeth of which serve to actuate thecounting wheel ofthe next decade and are angularlydisplaced by one pitch relative the teeth of the first-mentionedy gear wheel 35 in the direction of motion of the tens transfer member, is simultaneously caused to assume a position, in which it is momentaneously ready to'impart a moyement of one pitch to the counting wheel of the next decade when a rotary movement of further twofpitches4 is imparted tothe tens transfer member as a unit, tothe effect that thetens transfer member assumes a new initial position kfor the next transfer.

This last-mentioned' rotary movement corresponding to two `pitchesisimparted'to the tensl transfer member by a tooth 38y stationary mounted in thevv machine frame and arranged to cooperate with the gear wheel 36 during the rotation of 'the' frame 2 and spaeedjby such a distance from the axis of rotationfof the frame 2 ,ithat only when the tens transfer member withits gearwheel 36 assumes its preliminary positionr it` will contact` that tooth of' the gear wheel'36 whichhas beenfswung out from the axis of the frame 2in they preliminary position.

Besides countingwheels'andvtens transfer members the frame 2carries..enteringlwheels `41),.corresponding in number to the countingvt/,he'elsl and journalled to be freely rotatable on shortshaft piyots42s upported in lugs 41 on the frame 2, sothat" eachofssaid entering wheels will permanently mesh with one countingwheel -24. These entering wheels 4 0V arey only intended to facilitate the entering of the figures or. amounts toibe accumulated by the counting wheels.

As will be obv'ous.

a from'theforeg'oing text, the rotatable frame with'the adding mechanism vof the machine constitutes a normally cc'irnpletelyl free unit in the machine, which during: aness'ential`` part of its path of motion is not in counting engagementwiththe other machine parts, and,whichfmayjtherefore be taken out of the machine forL control' andadjuStirner:tt ifv necessary. The iiguresor amountst obe k accumulated by thel counting wheels 20-e24 ofthe ydifferent decades areentered into the accumulator andv thef'individual counting wheels during the rotation ofthe frame-2. Duringa certain part of said rotation eachfenteing.'wheel-40is caused to cooperate with teeth 51-59radially guided'in the machine frame and arranged in groupsfin-'thepath of motion of each entering wheel, said teeth pointing towards the axis of rotation of the frame 2.` In other words, each group of radially displaceable teeth 51-51 forms a fan around a portion of the periphery of the frame 2, and each tooth is provided with a laterally projecting pin 60 entering a guide slot 61 or a guide groove in the arcshaped amount setting wheel Il, which is adjustable, by means of special guidings not shown in the drawing by rotation about a centre coinciding with the axis of rotation of the frame 2. The groove or slot 61 in each amount setting member 1 is divided into two angularly displaced portions 6i and 61 of substantially the same arch length, said two portions having a common centre coinciding with the axis of rotation ofthe frame 2 but separate radii, so that the portion 61' is located nearer to the centre than the portion 61".

The two portions are Vforming a continuous groove by the provision of a rather steep submergion 62 between the opposite ends of the two portions. ySince the teeth 51-59 are radially displaceable only and their pins 60 co-operate with the slot or groove 61 in the amount setting member 1, the radial position of the teeth 51-59 will be determined by the fact whether the pins ofthe respective teeth are in engagement with the portion 61 or the portion 62 of the slot or groove 61, and the submergion 62 between the slot portions will form the point where the radial displacement of each tooth takes place. if the pins 60` of all the teeth 51-59 are in engagement with the outer slot vportion 62I in thepertinent amount setting member 1, all teeth of thisl group are inoperative. On the other hand, if the pins 60 of some of the teeth, for instance those of the teeth 51 and, 52, as shown in the drawing, are` caused to enter the inner slot portion61 due to the amount setting member being rotated a certain angle from` itszero position, said teeth 51 and 52A will be situated in the path of motion of the entering wheel 40 so that the entering wheel will be rotated by the operative teeth a number of pitches corresponding to the number` of operative teeth. (fin the drawing the teeth 51 and 52) when the frame 2 is turned one revolution, and a correspondingv rotary-motion is imparted to the counting wheel 20, 21, 22, 23 or 24 corresponding to the entering wheel in question;

As mentionedv already, one amount ksetting member 1 with pertaining. group of radially displaceable teeth having the function recently describedis provided for each one of the counting wheels 20-24 forming part of the portion of the machine, which shallY be usable for accumulation. To increase the addingy capacity of the machine, the frame 2 may of course be provided with a greater number of counting wheels with intermediate tens transfer members than what corresponds to the number of amount setting member-s 1, and in most cases this is even necessary, although it has not been shown in the drawing, amount setting members l: then being arranged for the counting wheels of some of; the first decades only. Thus it would be preferable inthe machine shown in thedrawing to-providel amount setting members of the type recently described fory theV countirigvwheels 20, 21 and 22'only, while the countingwheels 23 and 24 should serve merely, astens accumulation members in succession ashasbeen describedl already. However, this means no change in design of-thecounting wheels 23 and 24, and they-shall still-co-operate with entering wheels 40, which, however, are not performing any enteringfunction asfar as the latter counting wheels are concerned,4 TheV reason why, despite this, the entering wheels should be provided will appearI from the following text and'is. concerned with the zeroizing of the accumulator.l Thus,fthe-amountsettingmember 1 shown in the drawing-is-placedsoastoco-operatewith the counting wheel. 2,4 of thehighest decade only, because this facilitatesA the revealment of the machine mechanism. d

Each amount setting-member' 1 is made-inthe-form of an arched plate and is rigidlyf connected at its periphery to a corrugatedV operating body 65, which-.extends peripherically along'the amount setting"l member lover a-length at least corresponding to the rotability of the latter. Ori its outer side the operatingbodyr65y` carries figure marks 66 providedin `wave troughs thereon, which are serving as supports for; theiingers;atthe-manual operation of f thel amount setting t members. The operat-I ing body 65`co operates,with avrigid;support: edgei.67of the machine fra'melin-,sucha mannenthat by1 placing-a nger in the wave trough of the operating body marked with the figure to be entered into the machine and then turning the operating body and thus also the amount setting member until the finger placed in the wave trough comes to rest against the support edge 67, it is ensured that the corresponding number of teeth 51-59 is pushed in radially and will actuate the counting wheel of the corresponding decade at the rotation of the frame 2. In the drawing, by way of example, the wave trough carrying the Figure 2 has been moved down to the support edge 67 and the two teeth 51 and 52 have been brought into their operative position to co-operate with the counting wheel 24. To withdraw the operative teeth from their operative positions the setting member 1 is moved up (counterclockwise, Fig. l) to zero position by a hand manipulation of the operating body 65. This action restores all of the operative teeth to inoperative positions in which they are retained by the portion 62" of the cam groove 61.

On its inner edge facing the centre of rotation, each f amount setting member 1 is provided with an internal toothing 70, which is in permanent engagement with an operating gear 72 mounted on a stationary shaft 71, said gear 72 being freely rotatable on said shaft. Normally, each operating gear 72 is in mesh with an intermediate wheel 74 carried by an axially displaceable intermediate shaft 73. Each intermediate wheel 74 is connected with the common shaft 73 by a friction device 75, the operating gears 72 as well as the intermediate wheels 74 being axially non-displaceable relative their respective shafts.

The object of the friction device 75 will be explained later on in the text, and during the entering procedure the intermediate wheels 74 may be considered as freely rotatable-about the shaft 73, although against some resistance. Each intermediate wheel 74 in turn is in mesh with a type gear wheel 76, 77, 78, 79 or 80, which is rigidly connected with one of the type wheels 81, 82, 83, 84 or 85 in the indicating mechanism 4 of the machine, said mechanism consisting of a printing device, not illustrated in detail, for printing receipts or tickets. The type gear wheel 76 is connected with the type wheel 81, the type gear wheel 77 with the type wheel 82 etc. so that the type gear wheel 80 is connected with type wheel by means of telescopic shafts 86, corresponding in number to the type wheels, the tubular shaft 86, which connects the type gear wheel 80 with the type wheel 85, being the outermost one of all the telescopic shafts, as viewed in the radial direction. Thus, if the amount setting member for the counting wheel 20 is adjusted on a certain ligure, the type wheel 81 will be correspondingly adjusted, by the intermediary of the type gear wheel 76, the same thing being the case for all decades. If now the driving mechanism of the frame 2 is connected in any arbitrary way with the printing mechanism co-operating with the type wheels 81-85, the apparatus can be caused to print a receipt or a ticket indicating the amount which has been entered into the counting wheels and set by means of the amount setting members 1.

It might appear from the foregoing, that the machine can be caused to accumulate the amounts entered, continuously indicating said amounts, and to add them together to a total, the size of which is represented by the positions of the counting wheels 20-24 located in the frame. Accordingly, it would be possible to read olf the total of the entered amounts directly in the rotatmg frame 2 provided that the different counting wheels were eq uipped with gure marks, but this meets with certain lnconveniences since the frame 2 is not stationary and, besides, the counting Wheels are inconveniently positioned in the machine for being visually read off from the outside. Therefore, steps have been taken to allow a reading of the counting wheel positions via the indicating mechanism, i. e. the type wheel gear and the type wheels, to the effect that in the present case a receipt showing the total of the amounts entered into the machine is stamped out by the prining mechanism. In doing so, the accumulator must be emptied out into the set of type wheels, but it must be possible to reintroduce the amount from the latter to the accumulator for continued adding operation if desired, or it must otherwise be possible to zeroize both accumulator and type wheels after the emptying to allow a new series of adding 6 operations completely independent of those earlier effected.

The emptying takes place, when the frame 2 is in its position of rest, by means of a key 90 which is pushed in from the outside over a square end 91 on the shaft 14 carrying the counting wheels 20-24. With the key 90 the shaft 14 is turned one revolution in the direction opposite to that in which the counting wheels are moving during the accumulating operations, and the shaft 14 is axially displaceable against the action of a spring 92, the counting wheels 20-24 as already mentioned being axially non-displaceable in the frame 2. At the remote end of the shaft 14 is a radial pin 93, which normally engages a groove or recess 94 in the end portion of the frame 2, but when the shaft 14 is turned by means of the key 90, the pin 93 is moved out of the recess 94 so that an axial displacement of the shaft is effected. This axial displacement brings about the effect that during the rotation of the shaft rigid knobs 95 provided at the shaft 14 in a number corresponding to the number of counting wheels are caused to co-operate with an axially protruding lug 96 at each counting wheel 20-24 if the position of the counting wheel represents any other figure than zero, and the counting wheels are restored by the shaft to their zero-positions but not further, because the pin 93 then enters the recess 94 again, which allows the passing of the knobs 95 past the zero positions of the lugs 96. In order that the turning of the counting wheels shall not merely mean a zeroizing thereof when the shaft 14 is turned by means of the key 90, there is provided adjacent each type gear wheel 76-80 an axially displaceable but unturnable additional wheel 97, which is carried by the shaft 86 of the respective type gear wheel and is normally held at a certain axial distance from the type wheel by a spring 98, but is brought in engagement with the entering wheel 40 of the respective counting wheel if pressed against the pertaining gear wheel.

To prevent the amount setting members 1 from partaking in the movement and being turned at the emptying of the accumulator, the intermediate shaft 73 is besides arranged to be axially displaced in the direction to the right in the drawing, so that the intermediate wheels 74 at the intermediate shaft are released from the engagement with the respective operating gears 72 and will instead, like the entering wheels 40, engage the additional wheels 97 adjacent the different type gear wheels. 'Ihe motions of the additional wheels 97 and the intermediate shaft 73 with its intermediate wheels 74 are coordinated by means of a lever and fork mechanism 99, which is actuated by an axial displaceemnt to the right of the intermediate shaft 73. This axial displacement of the intermediate shaft is obtained mechanically at the co-operation of the key 90 with the shaft 14 thanks to a lever 100 which is swingably journalled in the machine frame and is actuated at its end 101 by a flange 90' on the key, said lever 100 being connected with the intermediate shaft 73. As soon as the key 90 is caused to co-operate with the counting wheel shaft 14, the intermediate shaft 73 and thanks to the lever and fork mechanism 99 also the additional wheels 97 are thus displaced so that the amount setting members are totally disengaged and the rotation of the counting wheels 20-24 will be transmitted to the respective type wheels 81--85. When the key is disengaged from the counting wheel shaft, the intermediate shaft as well as the additional wheels will return to their normal positions.

After the total amount entered into the machine has been stamped out or read oif in any arbitrary way through the type wheels 81-85, the latter are zeroized by turning the intermediate shaft 73 with the same key, the key effecting an axial previously described so that the amount setting members are disengaged. If now the intermediate shaft 73 is turned by means of the key 90, the intermediate wheels 74 taken along with the intermediate shaft under friction will turn the additional wheels 97 on the shafts of the type gear wheels to theeffect that the type wheels are restored to Zero position, the amount recently accumulated by the same simultaneously being returned unchanged to the respective counting wheels 20-24 via the additional wheels 97 and the entering wheels 40. The emptying of the accumulator with subsequent re-entering thus described may be performed whenever desired for controlling purposes,

' Vand the machine will always add every new-entered fig- .gaged from the entering wheels 46. Yrnediateshaft 73 is rotated by means of the key 90 while the push-button 1,05 .is all the time depressed, the type wheels 81-85 are zeroifzed without the gure values accumulated therein being returned to the counting wheels Ztl-24. .The moment the pressure on the push lbutton 105 ceases, its spring 106 restores the lever 161 .ure or amount to. the'v .total ofl those alreadyj accumulated.

In this connection it should be observed, that the machine mustbe equipped with one type` gear, wheel: with. pertaining type wheels. for each countingA wheel inrthemachine, and that also. the intermediate shaft 73 must be .provided withfriction-loaded .intermediate wheels; cor- Athe key9l0l is removedV from. the counting .wheel shaft 14, the rsprings 98 between the type gear wheels 'i6- 80 -and lthe. pertaining additional wheels 9.7 restoring the additional .wheels to .inoperative positions and simultaneously restoring, via the lever and fork mechanism .99, vwheels -74 to `normal position, at which moment the counting wheels in. the frame 2 are again entirely disthe intermediate shaft 73 with. its intermediate engaged. from the .type wheel4 gear and the amount set- `ting members. Instead of pressing the intermediate shaft 17-3 to the right in the drawing by means of the key 90. as

earlier described for the zeroizing of the type wheels S1-455, there. is depressed a .spring-actuated push -but- .ton 105, which. aetuates the lever 100 on the opposite side of its pivot axle .102, reckonedfrom. the intermediate shaft 73, so that the intermediate shaft 73. is displaced axially to the left in the drawing, the intermediate wheels 74 beingdisengaged from theoperating wheels 72 again ybut still maintaining their original engagement with1the type gear wheels 76, 77, 7S, 79 and 80. respectively by the latter having been given a` larger width o r axial length. VDuring this movement of the intermedi- ,ate shaft the lever and fork mechanism 99 remains in- -operative and thus does. not inuence the additional wheels 97, for which reason the latter remain disen- If now the interahd thus also the intermediate shaft 731v to the .normal position, in which the intermediate wheels .74, again serve to transmit the motions of the amount setting members to thetype gear wheels '76-30.

'It may be considered suitable to provide a checking rule for the type vgear wheels to .assure that the type wheels always are in the correct position for printing the lset amount. This checking rule may be shaped as a .swingable doctor blade parallel with the type gear shafts and entering the opening between two adjacent teeth in each type gear wheel thereby. preventing it froniturning as soon as the printing operation starts but again releasing the teeth as soon as the printing operation has ended.

Of course the invention is not confined to the embodiment shown in the drawing but may be varied with regard to size and design as well as to the arrangement of the parts. In a simpler construction of the machine, it is thinkable to dispense with the entering wheels 41) and accordingly also the operating wheels 72, and of course the type wheels 81-85 must not necessarily be printing wheels in a ticket or receipt printing machine, but may be adapted for direct visual reading through a window or the like, or may combine both these modifications.
